Abstract
A new wastewater treatment equipment, the bi-external recycling biological fluidized bed (BRBFB), which is an effective equipment, was investigated. Anaerobic digestion, aerobic aeration and settlement processes with a fixed sequential procedure were compacted into this reactor. By five different treatment courses, the optimization of the combined operation procedure in the system was determined to be a 12-hour cycle including an inflow process, a 4 h anaerobic digestion process, a 4 h aerobic aeration process, a 2 h settlement process and a 2 h recess process including effluent discharge process. By utilizing BRBFB to treat a synthetic dyeing wastewater, 90% of CODCr is removed for a higher-concentration water (CODCr 1 000–1 200 mg/L), and 82% of CODCr is removed for a lower-concentration water (CODCr 400–600 mg/L). Near 100% color is removal and discharging standards for industry wastewater are achieved.
